R. C. HOPKINS BLOWER FOR ATOMIZING OIL Filed 001;. l 1925 2 Sheets-Sheet 2 Zjwuantoz P0601! C l/apkins Patented Jan. 7, 1930 UNTTED STATES ROBERT C. HOPKINS, OF ALLIANCE, OI-IIO BLOWER FOR ATOMIZING OIL Application .filed October 1, 1925.

The invention relates to a motor blower for producing an air blast to atomize oil in a burner and to mix the air and oil for combustion.

The object of the improvement is to provide a blower communicating with an oil burner for furnishing a blast of air to the burner for atomizing oil, which may be supplied thereto in any usual manner, the mix ture of the atomized oil and air being in suitable proportions to support combustion, a heating jacket preferably surrounding the air pipe, and a heating drum being also provided to preheat the blast before it reaches the burner.

The blower may be operated by any suitable power means, but for the purpose of illustration the above and. other objects may be attained by associating the blower with an oil heated steam engine boiler, the blower being driven by a steam turbine operated by live steam from the boiler the air blast passing from the blower through an air heating drum surrounding the stack of the boiler and then to the burner, a heating jacket also surrounding a portion of the air pipe, the eX- haust steam from the engine passing through said jacket to the blast nozzle in the stack of the boiler.

An embodiment of the invention is illustrated in the accompanying drawings, in which Figure 1 is a side elevation of an oil heated boiler and steam engine showing the im proved blower mechanism associated therewith, and

Fig. 2, a top plan view of the same.

Similar numerals of reference indicate corresponding parts throughout the drawing.

A vertical steam boiler of usual construction is shown at 1, arranged to be heated by the oil burner 2 which is supplied with fuel oil, from any suitable source of supply, through the pipe 3. The upper end of the boiler is preferably conical as indicated at 4 Serial No. 59,8551.

terminating in the stack 5, the exhaust nozzle 6 exhausting into the stack for the induction of draft. A hot air drum 7 surrounds the stack and the conical upper end of the boiler.

Live steam from the boiler is carried 5 through the pipe 8 to the steam chest 9 of a steam engine 10, which may be of any usual construction. Exhaust steam from the en gine 10 is received in the pipe 11 which communicates with one end of a jacket 12 the other end of said jacket being connected to a pipe 13 which communicates with the exhaust nozzle 6.

A rotary blower 14, of any usual and well known construction, exhausts into a pipe 15 which leads through the jacket 12 and communicates with the heating drum 7, this pipe being preferably tangential to the heating drum and communicating with the lower portion thereof. 6

An outlet pipe 16, which is also preferably tangential to the heating drum, communicates with the upper reduced end portion of the same and leads to the burner 2 whereby a continuous blast of heated air is forced 6- through the burner, atomizing the oil and mixing with the same for combustion.

The blower 14 may be operated by any available power, and in the drawings a steam turbine 17 is illustrated as directly connected 5 to the blower, and driven by live steam from the boiler, which is conveyed to the turbine through a pipe 18, which may communicate with the steam pipe 8. The steam fromthe turbine exhausts through the pipe 19, which 86 may, if desired, be connected to the stack of the boiler to induce draft therein.

From the above description and an inspection of the accompanying drawings it is evident that a blast of air is provided for the oil 8 burner, the air being preheated by recuperation from the exhaust steam from the engine and radiation from the boiler while the blower may be operated by live steam from the boiler, the combination forming a self- 9 operated or self-energized unit.

I claim:

The combination with a steam engine, a steam boiler therefor and an oil burner for the boiler, of a blower, a conical air heating drum at the top of the boiler, a pipe connecting the blower to the lower portion of the drum, a jacket surrounding said pipe, means for passing exhaust steam from the engine through said jacket, and a pipe connecting the upper portion of the drum to the burner.

In testimony that I claim the above, I have hereunto subscribed my name.
